What do skiers really want? Powder. Light, dry, hissing powder. To be flown atop great swaths of it. And when the skies are too milky to fly? We still want powder. Which is why Selkirk Tangiers Heli should be on your life list. On down days, STHS comps tickets to Revelstoke Mountain Resort. Choose your days, choose your group, choose your lodging. (If your father-in-law’s buying, book Bighorn Lodge.)
